Abstract: A bicycle hydraulic operating device comprises a bracket, a hydraulic cylinder, a piston, a lever, a fluid reservoir, and a lid. The bracket is configured to be mounted to a bicycle handlebar. The piston is movably disposed within the hydraulic cylinder. The lever is pivotally provided around a pivot axis relative to the bracket and is operatively coupled to the piston to move the piston within the hydraulic cylinder in response to pivotal movement of the lever. The fluid reservoir is disposed on the bracket and having an opening configured to face substantially in a downward direction in a state where the bracket is mounted to the bicycle handlebar. The lid is configured to cover the opening of the fluid reservoir.

Abstract: A bicycle hydraulic operation device comprises a bracket, a hydraulic cylinder, a piston a lever, and a first biasing member. The bracket includes a gripping portion configured to be gripped by a rider. The piston is disposed within the hydraulic cylinder and movable between an initial position and an actuated position. The lever is pivotally mounted to the bracket around a first axis and operatively coupled to the piston to move the piston in response to pivotal movement of the lever from a rest position to an operated position. The first biasing member is operatively coupled to the piston and the lever outside the hydraulic cylinder such that the first biasing member biases the piston toward the initial position and biases the lever toward the rest position.

Abstract: A bicycle operating device comprises a base member, an operating member, and a hydraulic unit. The operating member is pivotally coupled to the base member about a pivot axis. The hydraulic unit is provided on the base member and comprises a hydraulic cylinder, a piston, and a hydraulic reservoir. The hydraulic cylinder includes a cylinder bore being at least partly provided above the pivot axis in a mounting state where the bicycle operating device is mounted to a bicycle. The piston is movably provided in the cylinder bore. The cylinder bore and the piston define a hydraulic chamber. The hydraulic reservoir includes a reservoir chamber connected to the hydraulic chamber. The reservoir chamber is provided above the cylinder bore without overlapping with the cylinder bore in a transverse direction parallel to the pivot axis in the mounting state.

Abstract: A non-metallic bracket for a bicycle hydraulic component is basically provided with a non-metallic body and a force receiving member. The non-metallic body has a hydraulic hose attachment port and an internal fluid passage. The hydraulic hose attachment port has an insertion opening disposed at an exterior surface of the non-metallic body and an internal attachment bore extending from the insertion opening towards the internal fluid passage. The internal attachment bore of the hydraulic hose attachment port includes an internal screw thread portion that threadedly receives a hose fastening fitting. The force receiving member is provided to the non-metallic body so as to receive force applied to the non-metallic body in an area of the hydraulic hose attachment port caused by screwing the hose fastening fitting into the internal screw thread portion of the non-metallic body.
